Abstract: To minimize the setup times in the case of a tool changeover on rolls, the movement sequences are separated into transverse movements and vertical movements using a tool changeover system and method for changeover of at least one tool disposed on a roll shaft in a working position. In one aspect, the tool changeover system includes a tool changeover rack, a vertical transport and a transverse transport. A drawing frame separate from the tool changeover rack can be transported transversely separately with reference to the tool changeover rack. The tool changeover rack has a device for connecting with the vertical transport and a tool accommodation for accommodating the tool. The drawing frame has a device for connecting with the transverse transport and a device for connecting with the tool.

Abstract: The invention relates to an underframe for a rail-borne vehicle for transporting freely movable loads, more specifically the underframe of a railroad crane. The underframe has a plurality of curve-negotiating wheel sets which are accommodated in bogies and mounted in a running-gear frame for rolling on running rails. A supporting-wheel set including two supporting wheels is provided to selectively relieve the load on the curve-negotiating wheel sets. The supporting-wheel set is fastened to the vehicle so that the supporting wheels may be raised to a rest position above the running rails and lowered from the rest position to an operative position in which the supporting wheel rests with adjustable pressure on the running rails.

Abstract: The invention pertains to a support for a track-bound crane vehicle, especially for a two-way crane vehicle for combined use on both roads and rails, which can be lifted from the tracks and set back down onto them by means of vertically-acting support cylinders, where, to distribute the support forces, each support cylinder is supported on a support plate. Each support plate horizontal bottom plate which can rest on the ground and a slide plate, which can slide over the top of the bottom plate. The upper surface of this slide plate is provided with a receptacle for a vertically-acting support cylinder.

Abstract: A road-rail crane includes a crane undercarriage with spreadable outriggers hinged to the undercarriage; a crane superstructure connected to the crane undercarriage with freedom of rotation, the luffing boom of the crane being mounted on the superstructure; and rail traveling gear attached to the crane undercarriage for rail travel. The crane undercarriage and the crane superstructure can be carried temporarily as a single transportable unit by a road transport means, which can be removed and then replaced by the rail traveling gear, which can be connected to the crane undercarriage, after the crane undercarriage has been supported and raised on the spread-out outriggers.
